Abstract

PROBLEM TO BE SOLVED: To obtain a mounting structure in which the gap between a base and an object to be mounted can be shortened by a method wherein a first mounting piece at a mounting spring is fixed, by a first fixing screw, to a mounting face formed along the axial direction of the base. SOLUTION: A second mounting piece 4B at a cross-shaped mounting spring 4 is extended and installed in a direction perpendicular to the axial direction of a base, and a first mounting piece 4A is bent so as to be extended and installed along the axial direction. Consequently, faces of the respective mounting pieces 4A, 4B are perpendicular to each other. On the other hand, a mounting face is formed in a direction along a shaft in the outer circumferential direction of the base. Then, when a rotation detector 1 is connected to an object 20 to be mounted, the mounting piece 4B is fixed to the object 20, to be mounted, by a second fixing screw 10, and the shaft of the detector 1 is coupled to the shaft of the object 20 to be mounted. Then, the mounting piece 4A is attached to the mounting face of the base by using a first fixing screw 5 from a side face. As a result, since the screw 5 can be attached from the side face, it is not required to set the gap D between the detector 1 and the object 20, to be mounted, so as to be large, and the detector 1 can be miniaturized.

It was difficult to reduce the entire length of the container 1 and the attached body 20. Also, as described above, the mounting spring 4
Must be attached to the rotation detector 1 before the rotation detector 1
And the attached body 20 could not be connected, the assembling method was limited, and the operation was extremely difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in particular, by fixing a mounting piece of a mounting spring to an outer peripheral side of a base of a rotation detector, the base and a mounting base are fixed. An object of the present invention is to provide a rotation detector mounting structure capable of reducing the distance between the body and the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a rotation detector mounting structure according to the present invention will be described below with reference to the drawings. The same or equivalent parts as those in the conventional example will be described with the same reference numerals. In FIGS. 1 and 2, a reference numeral 1 denotes a rotation detector including a known encoder, a resolver, or the like. A hollow rotation shaft 8 is mounted on a base 3 having a flange 2 of the rotation detector 1. It is provided rotatably. The base 3 contains a well-known optical encoder or resolver mechanism (not shown). The base 3 is provided with a mounting spring 4 having a substantially cross shape as a whole, and a rotary shaft 4 is rotatably penetrated through a center hole 4 a of the mounting spring 4.

The mounting spring 4 includes a pair of first mounting pieces 4.
A and a pair of second mounting pieces 4B are formed in a cross shape, the first mounting pieces 4A and the second mounting pieces 4B are formed at positions facing each other, and
The mounting pieces 4B extend in a direction orthogonal to the axial direction of the base 3, and each first mounting piece 4A is bent and extended along the axial direction. Accordingly, the surface directions of the mounting pieces 4A and 4B are different from each other, for example, orthogonal to each other. At the outer peripheral position of the base 3, a mounting surface 3a formed in a direction along the axial direction is formed.
Is located radially inward of the outer circumference of the. Each first mounting piece 4A of the mounting spring 4 is fixed to each mounting surface 3a with a first fixing screw 5.

Therefore, in the above-described configuration, when the rotation detector 1 and the body to be mounted 20 are connected, each of the second mounting pieces 4B
Is fixed to the mounting body 20 by the second fixing screw 10, the rotation shaft 8 of the rotation detector 1 is coupled to the shaft (not shown) of the mounting body 20, and finally, the first fixing screw is 5, the first mounting piece 4A is mounted on the mounting surface 3a of the base 3 of the rotation detector 1 to complete the process. Therefore, since the first fixing screw 5 can be attached from the side, the rotation detector 1 and the attached body 20 can be attached as in the conventional example of FIG.
There is no need to increase the gap D between the rotation detector 1 and the entire length of the rotation detector 1 and the attached body 20 can be shortened by shortening the gap D to achieve downsizing.

The mounting spring 4 is not limited to a configuration in which the overall shape is substantially a cross as shown in FIG.
The U-shaped configuration shown in FIG. 3 and the C-shaped configuration shown in FIG. 4 can also be used.

[0013]

Since the rotation detector mounting structure according to the present invention is configured as described above, the following effects can be obtained. That is, of the mounting pieces formed on the mounting spring, only the mounting piece that is fixed to the rotation detector side is bent and extended along the axial direction. Can be attached from the side to the rotation detector after it has been mounted, which is much easier than the conventional installation work, and the gap between the rotation detector and the body to be attached can be reduced more than before. And the overall length can be reduced.
